Aimé Guerlain, son of Pierre-François Pascal Guerlain, took over the House of Guerlain at the age of 27 when his father suffered poor health. To focus on his work in perfumery, Aimé turned over the management of the business to his brother, Gabriel. Gabriel's 16-year-old son, Jacques Guerlain — destined for fame in his own right — became Aimé's apprentice in the laboratory.
